Defeat to the All Blacks today would see England all but out of the competition following their 15-run defeat to West Indies.
But despite that setback, and the preceding humiliation of the record 90-run mauling at the hands of India in their final Group A match, Broad is still hopeful that his side can rally against New Zealand and then hosts Sri Lanka on Monday to win through to the semi-finals in Colombo.
“We hope we’ve got four games left in this ‘World Cup,’” he said.
“We back the guys up there (at the top of the order) — we know they’re all dangerous players.”
He added: “The next two games are must-win for us.
“That’s quite a good place to be in — you have clear targets of what you need to achieve. We’ve got two really huge games coming up, and we’ve got some really positive signs as well.
“We just need to put it all together in these next two games. If we do that, we’re in the semi-final of a World Cup.”
